I am 16, and I want to replace my stock muffler(single in/dual out) because #1 it has holes in each end,#2 it sounds too weak. I have a stock V8 350ci, Chevy P/U, with a stock cat. I want to replace the muffler with a flowmaster and run the dual pipes out the back(right now they are out the side) with chrome tips. I am considering the delta flow 40series or the forceII. I want something deep and powerful sounding at idle and to sound nice during acceleration, but yet not annoying while at cruisin speeds. Any suggestions?
